FOOT-PIECE.

Specification of Letters Patent.

Patented Mar. 16, 1920,

Application filed March 17, 1919. Serial No. 283,047.

To all whom it may concern:

Be it known that I, EZRA A. WOLFE, a citizen of the United States, residing at Morgantown, in the county of Monongalia and State of West Virginia, have invented a new and useful Foot-Piece, of which the following is a specification.

The device forming the subject matter of this application is a foot piece, adapted to constitute a part of a pumping mechanism of that type wherein air, being delivered through one pipe, forces a liquid out of another pipe, both pipes being carried by the foot piece.

The invention aims to provide novel means whereby air may be. supplied, and whereby it will be impossible to cut off the supply of air.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the invention appertains.

With the above and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, within the scope of what is claimed, changes in the precise embodiment of the invention shown can be made without departing from the spirit of the invention.

In the accompanying drawings Figure 1 shows in top plan, a device constructed in accordance with the invention, the pipes being shown in section; Fig. 2 is a longitudinal vertical section taken on the line 2-2 of Fig. 1; and Fig. 3 is a bottom plan, whereinthe closure has been removed, and wherein parts appear in section.

In carrying out the invention, there is provided a body 1, preferably made of metal, and including a reduced lateral extension 2. In the upper portion of the body 1, a main bore 3 is formed, the bore being reduced to form an auxiliary bore 4, there being a downwardly inclined circumscribing shoulder at the place where thebores 3 and 4 merge into each other. In the lower surface of the body 1 thereis a circumscribing groove 6. Inclined openings 7 are located in the shoulder 5 and form communications between the groove 6 and the main bore 3. A supplemental bore 8 is fashioned in t upper portion f the extension 2 of the body 1, the axes of the bores 8 and 3 being parallel. The lower end of the supplemental bore 8 communicates with one end of a transverse passage 9 in the extension 2, the inner end of the passage communicating with the circumscribing groove 6. The lower end of the groove 6 is cut off by an annular closure 10 cooperating with the lower end of the body 1. The closure 10 may be held in place in any desired way, but, in the present instance, it is provided with an annular rib 11 entering the lower part of the groove 6, the rib being threaded, as indicated at 11, to the body 1 within the groove 6. The lower end of a discharge pipe 14 is mounted by threading or otherwise in the main bore 3, an air inlet pipe 15 being threaded or otherwise'mountcd in the supplemental bore 8.

In practical operation, air is forced clownwardly through the pipe 15 and moves by way of the passage 9 into the groove 6. From the groove 6, the air passes through the openings 7 and forces the liquid in the 1 one of which extends entirely through the body, the other of which extends but part way through the body, there being a circumscribing groove in the lower end of the body about the first specified bore, the body being provided with a transverse passage connectingsaid other bore with the groove, and being provided with an opening leading from the groove to the first specified bore; and a removable closure for the groove mounted on the body.

2. A foot piece of the class described comprising a body having cooperating bores, one of which is reduced intermediate its ends to form a shoulder. the said bore extending entirely through the body, the other of said bores extending but part way through the body, there beinga circumscribving groove in the lower end of the body about the first specified bore, the body being provided With a transverse passage connecting said other bore with the groove, the body having an opening leading from the groove to the first specified bore and located below the shoulder; and a removable closure for the groove, assembled with the body.

In testimony that I claim the foregoing as my own, I have hereto afiixed my signa- 10 ture in the presence of two witnesses.
